切削刀具角度模型示教系统设计与制作-主副偏角与后角机构设计

Design and manufacture of cutting tool angle model teaching system-designof main and auxiliary declination and back angle mechanismAbstractTeaching system of cutting tool angle model (Teaching system of cutting tool anglemodel)is a teaching system that can intuitively and dynamically display the cutting angle ofthe tool.It is a small teaching model that can use the turning tool as a prototype to provideauxiliary teaching in the classroom.It can intuitively display the virtual plane of the cuttingtool:the base plane and the orthogonal plane;convert the virtual and abstract into a solid,Through the single-chip microcomputer,the motor and the transmission mechanism,the anglechanges of the main and auxiliary declination angle,rake angle and back angle are visuallydisplayed on the base plane,the orthogonal plane and the cutting plane;and the degree ofchange of the tool angle is directly reflected.Keywords:Cutting tool angle,angle change,visual display,mold teaching system
